I've seen this in both 6.9.1 and 7.0 RC1, but it looks like I can only select a single version as being affected, so I picked 7.0 arbitrarily. It appears that when using an OutlineView (and maybe other NetBeans platform tabular-type views; I'm not sure), if you sort them and get the triangular sort icon in the table header, the triangle is the opposite orientation of what it should be. So for example, if you sort ascending, the descending icon is shown, and vice-versa. Based on our testing, there does not seem to be an easy workaround such as reversing a comparator, since the comparator used seems to be the natural comparator on objects returned by RowModel#getValue(); for us these are the objects returned by Property#getValue(). Since those objects are often native types (like String objects) we have no control over that.
I see. Thunderbird on Linux uses the same arrow orientation for sorting as we have. But it really seems to be an exception. Other applications use up arrow for ascending sort order and down arrow for descending. I'll change the arrow orientation...
